Z '0 all whom it may concern:

Be it. known that I, STUART W, CRA'MER, a

"citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements in Air- Conditioning Apparatus; and I do hereby declare the following to be a full, clear, and

exact. description of the invention, such as Wlll enable others skilled in the art to which it apperlains to make and use the same.

This invention relates to apparatus for treating air, whereby the air is cleansed of its impurities, and is conditioned by the addition or subtraction of moisture and heat as may be desired.

The object of this invention is to provide an apparatus whereby air cleansing, moistoning, heating and cooling are attained as heretofore in similar types of apparatus, With the further advantage that cooling may also be continued even though moistening be discontinued, and Without the aid ofrcfrigeration, the circulationof cold water, or other on line 44 Fig. 3. V

liquids, or the like.

The invention consists in certain improvements which will be fully disclosed in the following specification and claims.

This application is adivision of my application for a patent filed April 15th, 1909, Serial Number 490,079. T I V In the accompanying drawings, which form part of this specification :Figure 1 represents a plan view partly in section on line 1-]. Fig.2 of apparatus embodying my invention, the air heating chamber being omitted... Fig. 2 a sectional elevation of the same: on line ;2-2 Fig. 1. Fig. 3 represents a plan view, partly in section on line 3-3 Fig. 4 of amodified form of the apparatus, and Fig. 4 a sectional elevationof the same 6 8' are tubes arranged within the cooling chamber and into which thespray heads are projected to saturate the air passing through the tubes, and constitute the separate spray or m oistening chambers.

9 are bafile plates or condensing bodies for collecting the surplus moisture from the spray laden incoming atmosphere and are arranged in the path of the moisture laden or frcighted air in transit toward the fan 13.

10 is the outlet for the spray charged air after it has passed through the spray chambers 2 in the tubes 8 in transit to the fan 13.

12 is :1V commingling chamber for the moistened air proceeding from the spray chambers 2 in the tubes 8 and from which it is discharged through the outlet 10.

14 are dampers separating the chamber 12 from the fan.

15 is a damper in the pipe 17 't0 control 1 the admission of moistened air, and 16 is a damper in the outlet 17 In this type of apparatus only one fan is used. The cooling chamber 3 is made the reverse from that shown in the construction illustrated and described in the parent application, spray passing through the'chambers 2 in the tubes instead of dry air. Furthermore, the tubes 8 are larger, into each of which is fitteda spray-head 7. The action'of thespray-head is not only to moisten and cool the air passing through the tubes 8, but also to create a draft through each tube by the inductive eifect of the spray. In

the construction above referred to, the cooled and moistened air is either conducted into the fan and thence into the ducts for delivery into the building through outlet-20,

or by the use of the dampers 14 and'16, is

directed outside the building as may be desired, in the latter case, the outside damper 16 being preferably in an outlet 17' at the top of the chamber receiving the spray and the air currents from each 'of the spray. tubes.

The type of apparatus shown in Figs. 1 and 2, is technically what is termed the Draw-through type, i. e. the fan draws the air through the heating and cooling chambers and around the heater coils, not shown in said Figs. 1 and 2.

Figs. 3 and 4 illustrate the application of this type of apparatus to what is termed .the Blow-through type. The direction of the air in transit is indicated by arrows which make plain the operation. In the preferred construction, shown, however, the

dry air is blown through and the moistened.

air is drawn through the apparatus Whenever it is to be introduced in a mill or apartment.

' In the construction shown in Figs. 3 and 4, saturated air from the tubes 8 passes into the chamber 12, from which it is drawn through passage 10 into the fan 18, is forced outward around said tubes 8 in chamber 8 and discharged through outlet into the building.

Having thus fully described my invention, What I claim is- 1. In an air conditioning apparatus, an air chamber, tubes Within said chamber, spray heads for moistening, cooling and inducing a current of air through said tubes, a fan, and means for varying the mixture of air proceeding from the air chamber and from the spray tubes.

2. In an air conditioning apparatus, an air chamber, tubes Within said chamber, spray heads for moistening, cooling and inducing a current of air through said tubes, a fan, and means for separating the air proceeding from the air chamber and the moistened air from the tubes.

3. In an air conditloning apparatus, an air chamber, a plurality of spray chambers
